List of UK judgments relating to excluded subject matter
# List of UK judgments relating to excluded subject matter

Under United Kingdom patent law, a patent may only be granted for "an invention". While the meaning of invention is not defined, certain things are not regarded as inventions. Such things are excluded from patentability. This article lists judgments delivered by the UK courts that deal with excluded subject matter.

The provisions about what are not to be regarded as inventions are not easy. There has been and continues to be much debate about them and about decisions on them given by national courts and the Boards of Appeal of the European Patent Office. This article also list some of the discussions that have been had about the different judgments.

## Law

Article 52 of the European Patent Convention, which represents the source of UK law in this area and which should have the same meaning states that:

    (1) European patents shall be granted for any inventions, in all fields of technology, provided that they are new, involve an inventive step and are susceptible of industrial application.
    (2) The following in particular shall not be regarded as inventions within the meaning of paragraph 1:
       (a) discoveries, scientific theories and mathematical methods;
       (b) aesthetic creations;
       (c) schemes, rules and methods for performing mental acts, playing games or doing business, and programs for computers;
       (d) presentations of information.
    (3) Paragraph 2 shall exclude the patentability of the subject-matter or activities referred to therein only to the extent to which a European patent application or European patent relates to such subject-matter or activities as such.

* Categories in green were judged on but the (alleged) invention was found not to fall into that category.
* Categories in red were judged on and the (alleged) invention was found to fall into that category; hence the claimed invention was excluded.
